M112 8 Rib pulleys for magnuson blower

[ARUJLS]

Hey, I'm wondering if any one has an 8 rib pulley for a older magnuson m112 blower and also rear pulleys. I am getting belt slip and am loosing boost. Looking for the 2.8in or smaller and am trying tonget 10psi out of it.
If you know of anyone that may have them could you direct them my way.

Thanks
Brett
